Sustainability of a manufacturing system defines its efficiency and productivity. In the world of ever growing energy requirements and depleting resources the need of sustainability is greater than ever. Present research was undertaken to analyze sustainability of turning aerospace alloy Ti-6Al-4V under different cutting conditions including dry, wet and cryogenic. Feed rate, cutting speed and depth of cut were taken as input variables along with cutting condition. Specific cutting energy was analyzed under varying machining parameters. It was found that energy consumption under cryogenic conditions was lower than dry and wet conditions. At speed of 50 m/min cryogenic turning energy consumption was 9% lower than dry cutting and 16% lower than wet cutting.

This paper focused on the effect of thermosyphon limits on the design of a taper thermosyphon drill for dry drilling operation. Although, other methods such as minimum quantity lubrication have been sought but the harmful effects of metal working fluids persist. This study however focuses on the design, fabrication and testing of a thermosyphon drill for eliminating the use of metal working fluids in drilling operations. The methodology included the design of a taper thermosyphon drill, analysis of the thermosyphon drill, manufacturing and testing of the thermosyphon drill. A virtual design and stress analysis of the reversed tapered thermosyphon was done using SolidWorks software. A high speed steel drill bit was manufactured to suit the design requirements of the thermosyphon. The thermosiphon was then fabricated within the machine shop floor using Electric Discharge Machining through method of spark erosion. A reverse tapered thermosyphon was designed to improve the optimal performance of the drill. The reversed tapered thermosyphon specification includes a 20 mm diameter drill, a length of 140 mm and web thickness 7mm, with a taper thermosyphon of 6.48 mm large diameter and 2.5 mm small diameter on a length of 114 mm. The optimal position stress analysis shows that the tapered thermosyphon drill experienced a Von Mises Stress of 38.4 MPa for the cutting distance from the drill tip and 372°C for the optimal temperature. The optimal position stress analysis also showed a Von Mises Stress of 17 MPa for the largest taper diameter and 433°C for the optimal temperature. The thermosyphon drill bit was manufactured and tested against the dry drill and metal working fluid drill bit. The results displayed a reduction in drill bit peak temperatures on the drill bit tip of about 40% for the dry drilling and thermosiphon drilling processes.

The analysis of old mortars is performed for either conservation, repair or the compatible restoration of heritage buildings. It includes experimental analysis of original materials from historic buildings using the non-destructive methods. The methods such as visual investigation, color test, cohesion test and microscopic analysis are considered the most cost-effective methods for determining the composition of heritage mortars. The paper reports the results of an experimental investigation into the physical properties of the cementing materials from the oldest colonial building in South Africa; Castle of Good Hope. The original materials from the Castle were made of lime as a binder, fragments of seashells as additives and soil mortars without a binder. The physical characterization of original heritage mortars gives details of the binder type and the aggregate type which may help to achieve sustainable restoration of ancient buildings.

Mechatronic system design includes a combination of different engineering disciplines. A common approach in design of mechatronic systems is based on a sequential method, where different disciplines are treated and designed separately. This paper extends earlier work on integrated physical and control design optimization with integrating an additional aspect of the corresponding embedded control system implementation. Our previous publications describe integrated design optimization through a few specific use cases but the impact of embedded control implementation on the structural design of the systems is neglected. In this paper, the approach is extended to cover discussions on control implementation and its effect on the physical dimensioning and vice versa. A multi-objective optimization approach is implemented and tested on a mechatronic system case study consisting of a DC-motor, a planetary gear, a flexible shaft, an embedded controller and a load. The couplings between the properties of different engineering domains are studied and highlighted. The presented approach which is aimed for early phases of design, considers the integration of three engineering disciplines in one design framework which so far has been missing.

There has been great research interest for memristors worldwide as it has many potential applications. Resistive memories based on metal oxide thin films have been extensively studied for application as next generation nonvolatile memory devices since they have several advantages, such as good scalability, low-power consumption, and fast switching speed. However, the fabrication of metal oxide based memristors usually consists of conventional physical vapor deposition (PVD) techniques and lithography which are expensive, time consuming and complicated in nature. In this paper, we report the successful fabrication of ZrO2 based memristor using electrospray deposition (ESD) and electrohydrodynamic printing (EHDP) techniques which are cost-effective, room temperature techniques. The Ag electrode has been patterned on glass substrates through EHDP technique and the active layer of ZrO2 has been spray deposited on the Ag electrode followed by the patterning of top Ag electrode. The resistive switching properties of ZrO2 layer with Ag electrodes was investigated in this study.

The accumulative roll-bonding process (ARB) was performed on commercially available AL-1050-H4 aluminum alloy. Samples were rolled for two passes. In ARB process, thickness is reduced by 50% for each pass. The aim of performing the ARB process was to refine the grain structure of aluminum 1050-H4 to increase its tensile strength. A tensile test was performed at room temperature and at a steady strain rate with the aim of determining whether ARB increases the mechanical properties of aluminum 1050-H4 and identify the moment the material experience high ultimate tensile strength. Samples were cut according to standard test methods for tension testing of metallic material (ASTM) at rolling direction (RD). Information about the microstructure of samples was obtained using a scanning electron microscope (SEM). The highest UTS was obtained on the 1st pass and was reported as 127.1 MPa and the lowest UTS was discovered on parent sample and reported as 111.7 MPa. It was also observed that E-modulus and percentage elongation decreased due to the ARB process. It was noticed that after several rolling process, material surface temperature increases. The increase in surface temperature led to increase in particle size which was discovered on 2nd pass of ARB process which result in material losing its mechanical properties

With the advancing digitalization of production plants, it becomes possible to use process data across machine boundaries. A machine can adapt its parameters to another machine-measured parameter to increase product quality. The present paper describes the design of an inter-machine control loop with machine learning techniques in order to improve the final quality output. The production ramp-up represents a special application case for this since at this point of time there is only limited knowledge about cause-effect relationships. For this purpose, the paper presents a method for analyzing these interrelations. On the one hand, simple linear regression is used to analyze the linear relationships; on the other hand, machine learning algorithms are used to analyze non-linear relationships. Two independent control loops form the overall control loop, which is capable of deriving holistic prognoses on upstream or downstream process effects.
